Determine if a given point is a solution to a linear function

Objective: SWBAT define and graph linear functions

Big Idea:
Is the kid "on the line" or not? :)
Get kids to figure out whether a given point is a solution to a linear function by defining what a solution is -- namely, an ordered pair that makes the function true.

Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

For a video narrative about how I structure each lesson, and how the warm-up fits in, click Warm UP.

In this case, the warm-up gives the chance for kids to practice graphing from the previous day, while isolating y first.
